Indigenous

Deeper contamination may be remedied with bioventing, where air is injected through some wells, and extracted through others to both strip volatiles and provide oxygen to indigenous organisms. Fertilizer nutrients may also be added. This is usually only a viable option with lighter refined products. 

Gloves. The clove spice is the dried unopened buds of the evergreen tree, Eugenia caryophyllus Thumb (Myrtaceae). This tree is also called Sj gium aromaticum L. Other botanical names are used, but some discrepancies exist as to the proper nomenclature. The tree is indigenous to the Molucca Islands. 

Sesame Seed (Benne, Benni, Bene Seed). Sesame seed is the whole dried seed of Sesamum indicum L. (PedaUaceae), an annual plant now cultivated in Mexico and Central America, although indigenous to Indonesia and tropical Africa. It may be the oldest condiment known. The seed is small, shiny, and oval shaped, about 0.32 cm long. The unhuUed seeds are dark and the hulled seeds are pearly white. Sesame seeds, when baked, have a pleasant, roasted, nutty flavor. They are used in baked goods and in confections, eg, halvah. 

Although nuts have been a staple food in many countries for generations, their status in the United States as a chief food crop is relatively recent. The main suppher of Knglish walnuts, filberts, and almonds had been Europe. However, pecans and black walnuts are indigenous to North America, and the United States is the principal producer of pecans. Other U.S. nuts, such as beech, butternut, white walnut, American chestnut, chinquapins, hickory, picon, and northern California black walnut, are utilized mainly for local consumption. Chestnuts and chinquapins are susceptible to the chestnut blight fungus, Endothiaparasitica which has virtually destroyed the American chestnut (152). 

Amyris Oil. Obtained by steam distillation of the wood of y m hakamijera L., the so-called West Indian sandalwood which is indigenous to northern South America, Central America, and the West Indies, amyris oil [8015-65-4] is a pale yellow to brownish yellow viscous oil with a slightly oily-sweet and occasionally peppery balsamic woody note. It finds use as a blender and fixative for soap fragrances. The volatile constituents, which are primarily hydrocarbon and oxygenated sesquiterpenes, are shown in Table 22 and Figure 5 (63). 

Bay Oil. Steam distillation of the leaves of the tree Pimenta racemosa (Mill) which is indigenous to certain islands of the West Indies, particularly Dominica and Puerto Rico, is called bay or bay leaf oil. The same source was used in the past to produce Bay Rum in which mm was distilled over the leaves. Bay oil [8006-78-8] is a yellowish to dark brown mobile Hquid with a fresh-spicy, sometimes medicinal odor with a lasting sweet-balsamic undertone. The oil finds extensive use in hair tonics, after-shave lotions as well as other men s-type fragrances. There is Htde or no use by the flavor industry. The range of components for a number of bay leaf oils is shown in Table 25 (66). 

Opium is the dried, powdered sap of the unripe seed pod of Papaver somniferum, a poppy plant indigenous to Asia minor. Theophrastus described its medical properties in the third century BC, but the Sumerians, ca BC 4000, probably perceived its utility. Arab physicians knew of the dmg, and Arab traders carried it to the Orient where it was used as a treatment for dysentery. Paracelsus is credited with repopularizing the dmg in western Europe in the early sixteenth century by formulating opium into "laudanum", which is still in use. More than 20 different alkaloids (qv) of two different classes comprise 25% of the weight of dry opium. The benzylisoquinolines, characterized by papaverine [58-74-2] (1.0%), a smooth muscle relaxant, and noscapine [128-62-1] (6.0%), an antitussive agent, do not have any analgesic effects. The phenanthrenes, the second group, are the more common and include 10% morphine (1, = R = H), 0.5% codeine [76-57-3], C gH2 N03, (1, R = H, R = CH3), and 0.2 thebaine [115-37-7], C 2H2 N03, (2).
